Outline of Final Research Achievements

Electric conductive polymer was coated on non- or low electric conductive ceramic fibers to improve their surface electric conductivity, and novel interphase-formation process for high performance ceramic-based composites based on electrophoretic deposition (EPD), i.e. electrochemical approach, was developed. As a result, it is demonstrated that the surface electric conductivity of low electric conductive ceramic fibers was improved by the thin electric conductive polymer coating, and EPD can be successfully applied for interphase-formation on the fibers. Furthermore, interphase-formation process for ceramic-based composites with excellent mechanical properties can be achieved by EPD process.
